Question

Using the graph, calculate the car's acceleration.
A) 0.12 m/$s^{2}$
B) 0.13 m/$s^{2}$
C) 7.5 m/$s^{2}$
D) 8.3 m/$s^{2}$

Answer 1

Answer:

Option C. $7.5\frac{m}{s^{2}}$

Step-by-step explanation:

we know that

The car's acceleration is equal to the difference between the initial and final velocities, divided by the time

In this problem

Let

$A(0,0), B(6,45)$

therefore

$a=\frac{45-0}{6-0}=7.5\frac{m}{s^{2}}$
